23rd Annual Summergrass Festival

Summergrass Bluegrass Festival 2026

A three-day bluegrass campout festival presented by the Antique Gas & Steam Engine Museum in Vista, California. Grab your lawn chairs, gather around the stage, and soak in the sounds of world-class bluegrass music under the open sky.

With non-stop picking, jamming, and good old-fashioned community spirit, Summergrass brings together musicians and fans from across the region for a weekend celebration of traditional and contemporary bluegrass. Camp out on the museum’s scenic grounds, explore the historic exhibits, enjoy delicious food from local vendors, and experience the kind of laid-back, family-friendly atmosphere that has made this festival a beloved Southern California tradition for over two decades.
